I've been working on a simple raycasting engine for a while now, and I ran into a slightly sticky math problem (how to find the exact position at which a ray first intersects one of the blocks). To find that out, I really only need to know this: what's the fastest way to find out which *side* the ray has struck?

Thanks in advance!
